Ergonomic and human factors affecting anesthetic vigilance and monitoring performance in the operating room environment.
Weinger MB, Englund CE. Anesthesiology. 1990;73:995-1021.
This review discusses the important role ergonomic and human factors should play in ensuring safe anesthetic care, drawing on literature from non-health care settings. The authors begin by discussing errors in anesthesia and the opportunities created for such errors by the inevitable nature of the job. They continue by presenting a framework for the contributing factors, which include the work environment (eg, noise, lighting, temperature), the human component (eg, team factors, fatigue, workload), and the equipment and system component (eg, alarms, automation). The authors advocate for greater attention to these contributing factors and further study based on the experiences of other high-risk, error-prone industries.

Gilbreth FB. Can J Med Surg. 1916;40:22-31.
This study was one of the first "time-motion" studies of physicians, and pioneered the application of human factors engineering and industrial principles to medical practice. The authors shadowed surgeons, who are described as "the most interesting of all mechanics," at hospitals in the United States, Canada, and Germany. Based on their observations, the authors identified the components of the work day as "necessary work," "unnecessary work," "avoidable delay," and "unavoidable delay." In order to maximize the efficiency of a typical surgical practice, they argue for standardization of surgical equipment and the hospital environment, recommend scheduled rest periods to avoid fatigue, and advocate for using technology to avoid fatigue arising from necessary work.
